What I'm looking for

I'm looking to build scalable, reliable Android products with cross-functional teams, solving performance, resiliency, and user-experience challenges in high-impact mobile applications.

At Walmart Global Technology, I build scalable Android solutions for the Walmart Pharmacy platform, focusing on performance, stability, resiliency, and maintainability. I develop production features using Kotlin, MVVM, Coroutines, modular architecture, and RESTful APIs.

Previously at Samsung R&D, I developed Samsung Contacts and Samsung Wallet for more than 1 billion active users globally. I improved stability by reducing ANRs and crashes, optimizing memory and background workflows, and supporting responsive experiences across 150+ device models.

I've built health, fitness, prescription refill, order-management, and vaccine-scheduling workflows. My work includes reusable multiplatform networking, repository, and domain modules shared across Android and iOS.

I enjoy collaborating with backend, QA, and product teams to deliver reliable software, strengthen automation and regression testing, and improve release quality.
